In spite of the discouraging diagnosis, the musician insisted that her doctors believe she will be able to sing once again after extensive treatment.

"Apparently, I will sing again," Twain said. "It will take a lot of work. I've gotten to the bottom of it [now]."

She continued: "I've discovered a lot... The 'Why Not?' tour [promoting her OWN series]... was a whole educational experience for me. [I learned] what was wrong and what I can do about it by identifying [the cause]."

Twain added: "It's that genuine choked up feeling that when you go to speak at a moment of anxiety, a squeak comes out or something that surprises you that's not really your voice."
